The 598g S is based on Nvidia's 1GHz Tegra 2 processor, and will come in 'Wi-Fi only' and 'Wi-Fi plus 3G' versions.

The clamshell P has two 5.5in, 1024 x 480 touchscreens - think of it as a Psion Series 5 with a touchscreen instead of a keyboard - and will connect to both Wi-Fi and 3G networks. Weighing just 372g, it's just 26mm thick when closed. It too has a 1GHz Tegra 2 on board.

Both gadgets have front- and rear-facing cameras, SD slots and USB 2.0 ports. The Wi-Fi spec is single-antenna 802.11n.

Both are PlayStation Certified, so will run Android-hosted games.

The Wi-Fi only S will ship first, around mid-September, with Android 3.1 Honeycomb. The version with 3G - and the P - will ship in November with Android 3.2, to which the Wi-Fi only S will be upgradeable. ®
